H. A. ALLEN- SANITARY DISPENSER Filed Dec. 4', 1939 ATTORNEYS PatentedNov. 19, 1940 UNITED STATES PATENT OFFICE 2 Claims.

This invention relates to sanitary dispensers and has for an object toprovide a dispenser for liquids and semi-liquids such as catsup bottles,bulk oil cans, medicine bottles, molasses cans and other containers,adapted to prevent the contents spilling over and running down the sidesof the container after the pouring operation.

A further object is to provide a device of this character essentiallycomprising an outer tubular member adapted to be inserted into the neckof the container, an inner tubular member mounted concentrically in theouter member by means of radially extending fins, and a' valve slidablymounted on the inner tubular member, the arrangement such that whenpouring the contents from the container, due to closing of the valve,the contents can only pass through the inner tubular member and when thecontainer is returned to upright normal position any drip from the innertubular member may pass back into the container through the open valve.

A further object is to provide a device of this character which will beformed of a few strong simple and durable parts, which will beinexpensive to manufacture, and which will not easily get out of order.

With the above and other objects in view the invention consists ofcertain novel details of construction and combinations of partshereinafter fully described and claimed, it being understood thatvarious modifications may be resorted to within the scope of theappended claims without departing from the spirit or sacrificing any ofthe advantages of the invention.

In the accompanying drawing forming a part of this specification:

Figure 1 is a longitudinal sectional view of the neck of a bottleequipped with a sanitary dispenser constructed in accordance with theinvention and showing the dispenser in elevation.

Figure 2 is a longitudinal sectional view of the bottle neck anddispenser.

Figure 3 is a cross sectional view taken on the line 3-3 of Figure 2.

Figure 4 is a longitudinal sectional view of the bottle neck and aportion of the dispenser and showing a cork stopper for the bottle neckand dispenser.

Figure 5 is a bottom plan view of the cork.

Referring now to the drawing in which like characters of referencedesignate similar parts in the various views, Ill designates the neck ofa container such as a catsup bottle. The dispenser comprises an outertubular member I! equipped at the top with a flange l2 adapted to abutthe top edge of the bottle neck. Mounted concentrically in the outertubular member II is an inner tubular member I3 having fins 14 securedto the inner surface of the outer tubular member in any preferred mannerto space the inner tubular member from the outer tubular" member. Thelower end of the inner tubular member terminates in a flared flange l5.The inner tubular member extends above and below the outer tubularmember.

Slidably mounted on the inner tubular member below the outer tubularmember is a washer forming a valve Hi. The washer is preferably formedof rubber and is provided at the bottom with a flared resilient skirtll. When the bottle is inverted to pouring position the valve closes thespace between the two tubular members as shown by dotted lines in Figure2, and the contents are dispensed through the inner tubular member.

A cork stopper l8 isprovided for sealing the bottle and dispenser whennot in use. The stopper is provided with an axial bore 19 which looselyreceives the top of the inner tubular member H3. The stopper is providedat the center of the inner wall of the bore with an integral projection20 of sufficient diameter to snugly fit within the end of the innertubular member. Thus the cork seals both the dispenser and the neck ofthe bottle.

In pouring the contents from a bottle equipped with the device, due toclosing of the valve, the contents may only pass through the inner tubel3. However, when the bottle is righted any drip from the inner tube maypass back into the bottom through the outer tube and open valve. Due tothe flexibility of the skirt ll of the valve, when the bottle isinverted to pouring position a suction will be created against theskirt, then when the bottle is turned upright again that suction willdraw the valve down to its open position, assisted by gravity.

From the above description it is thought that the construction andoperation of the invention will be fully understood without furtherexplanation.

What is claimed is:

1. A sanitary dispenser for liquids and semiliquids comprising an outerflanged tubular member adapted to be inserted into the neck of acontainer, an inner tubular member disposed concentrically Within theouter member, fins connecting the inner member with the outer member,said inner member extending above and below the outer member andterminating at the lower end in a flared flange, and a disc valveslidably mounted on the inner member between the and outer member andthrough the open valve flared flange and the lower end of the outer whenthe container is restored to normal position. member and adapted. toclose the space between 2.
